ROBERT G. CAMPBELL, OF GREENSBORO, NORTH CAROLINA.

APPARATUS FOR TREATING- TEXTILE FIBERS.

To all whom it may concern/:1

Be it known that I, ROBERT G. CAMPBELL,

a citizen of the United States, residing at Greensboro, in the county ofGuilford and State of North Carolina, have invented certain new anduseful Improvements inA pav Textile Fibers; and% do hereby declare t efollowin to be a full, clear, and exact descri tion 0 the invention,such as will enable ot ers skilled in the art to which it appertains tomake and use the same.

My invention relates to the treatment of textile fibers, such as yarnsand warp, has especial reference to dyeing such fibers, has for itsObjecteconomy in time, labor, and

dyeing material, by subjecting the fibers in the form of warp, frombeams to the dyeing material while. in transit through the vat, andagain winding the warp upon other beams as it proceeds from the vat, 1ncontra distinction to subjecting the material in bulk to the dye liquoror drawing; the warp charging t e warp from the vat into cans or mentswhich will be fully disclosed in t e followin specification and claims.

In he revailing practice of dyeing textile fibers in ulk, it ispracticalli im ossible to or o the material, for-the reason, that allthe material is not exposed alike to the dye 'li uor; the material inthe center of the bulk eing less exosed to the liquor than the outerortions. urthermore, considerable waste 1 material occurs, by breakingand tangling ,of the fiber, yarn or warp, in winding or balling themupon beams.v

Warp usually contains from four hundred and fifty to five hundredthreads or ends and is from four thousand to four thousand five hundredyards long, and theprevailin practice of d eing warp other than in bu]consists in ra-wing the warp out of the boiling vat and depositing it incans or boxes, in

which the vwarp is distributed evenly and pressed down by hand, and asmany cans are used as are necessary to contain the warp of a set. Thecans are placed upon a true in sets of four and conveyed to the dyeingvats and placed in position for the warp to be conducted through the d eliquor by the use of friction or pressing rol ers, which draw the warpthrough the liquor of the first vat and Specification of Letters Patent.7 Application filed February 16, B506. Serial No. 301,484.

deposit the warp in other like "cans.

The 1 warp in coming from the cans frequently.

becomes tangled and requires the attention of a workman for each set offour cans from which boiled Warp is being drawn to untangle the warp torevent breaking and kinking of the threa s, rolls.

The warp passing through the several 01' choking the feed vats, from sixto eight in number, to get the labor and consuming much time, be-

posited in cans must be moved to another vat by manual labor, thusrequiring from six to eight handlings, and the .time 'c nsumed in dyeina set of warps is two days and a half, whi e by the present invention,no handling of the warp is required, and the dyeing is com leted in oneday. The warp is kept under t e same'tension from the time it is unwoundfrom the beams on which it is supported until it is wound again uponother beams after'ithaslbeen dyed.

It is my u ose 'to treat the fibers, inseparate stran s o warppreferably four to a set, for boiling, bleaching, dyeing, washing-ormercerizing while in motion, and being un- 'wound from one beam, reel ors ool, con-.

ducted 'throughfthe liquor .for e1t er, or all thepurposes, and. againwound upon other beams, reels or spools as it proceeds from the vat orvats.

In the accompanyin drawings, which form part of this specification:Figure 1 represents a sideelevatiom of :ny improved apparatus, the sideof; the vat being partly broken away. Figs. 2, 25 and 2 are'like viewsof the same on an enlarged scale. Figs. 3, 3' and 3 are plan views ofthe same. Fig. 4 a side elevation partly in section of the ioo traverseor carriage forgiiiding the warp t0 the beams for winding or ballingafter it has been treated in the'vat, on an enlarged scale. .Fig. 5 anend elevation partly in section, of

the same, and Fig. 6 an enlargedivertical transverse section of the warpfeed-and pressn ro'lls. i

Reference being had to the drawingsand the designating charactersthereon, the

,, a separate ,revolub numeral 1 indicates the frames on which the warpbeams 2 aresupported by their'axlejournals 3 resting in suitablebearings 4 in the upper edge of the frames. The frames are securedtogether by transverse rods or bolts 4 5 indicates an elevated frame,

preferably suspended from the ceiling of a -vent interference of thewarp, their shafts Qhb e'ing supported suitablebe'aring's, not s 0secured to the inner si i or the sides ldfofthe vat.

- 6' is a su plemental vat on one side of vat 6, and of w iijiehtheremay be any preferred number found necessary or advantageous in theuse to" which the ap 'aratuS i applied The supplemental vat a so providewith separate revoluble guide sheaves 8' having shafts 9".

1'1 indicates guide fil'lgers whieh are secured on the; top of t e outerend of the vat and ex-' tend inward to guide the warp 12' to the lower seaves 8 or 8 at the outer end of the vat, from which sheaves the warptravels horizontally, then upward over the successive sheaves to theunderside of the [upper sheaves at the inner end of the vat.

13 and 13 indicate a pair of rolls mounted infsuitab'le pedestals 14:,14 resting on the top edge of each side of the vats 6, and 6, and neartheinner end thereof. The rolls may be made of hard wood or of metal,and the upper'r'oll 15 is preferably covered with rubber, cloth or othersuitable material 15, and the pressure upon the top rolls, operates tosqueeze or press the dye liquor out of the Warp and draw the warp fromthe beams'2, through the vat. The ressure is regulated by :lev'ers 16,fulcrumeg at 17,; engaging a block 18, resting upon the shaft 19 of thetop roll, and provided with a weight 20,- adjustable on the lever toregulate the degree or amount of pressure on the warp.

The rolls 13 and 13 are driven by power transmitted from asuitablesource, through pulley .21 on shaft 22, belt 23, and pulley 24on shaft 25, on which is secured a pinion 26,

' which engages a gear-wheel 27 on the shaft 28 of the lower roll. Theshaft is supported-on brackets 29 on'the" pedestals 14, as shown inFigs. 3? and 6, and extends across the vets 6 and 6' to drive the twosets of rolls synchronously. whereby the work of drawing the warp' is.effected by the joint operationof the two sets of rolls and the warp iskept under the same tension in both vat-s.

30 indicates a plurality or guide sheaves, one for each warp separatelyrevoluble on shaft 70, supported from the ceiling in any preferredmanner, such as by hangers 29 above the frame 5 and beyond the inner endof the'vat 6, over which the strands of warp are conducted from therolls 13. 31 is another likeset of sheaves revoluble on shaft 71supported by like hangers 29" above the outer end of vat 6, as shown inFigs. 2 and 3",

over which the warp travels on its way to' vat '6', then travels overthe several sheaves 8' said vat successively, like manner in which ittraveled over the sheaves 8 in vat 6,

emerges therefrom'and'passes through the rolls 13 on the vat 6, by whichthe warpis -drawn'and travelsto the guide sheaves 31 above thewarpwinding machine 32, where the strands of warp are separated and two ofthe strands are wound respectively upon beams 33 and 34, supported uponaxles 35 and 36..

The distance between the inner end of the vat 6 and the outer end of thevat 6. and the time re 'uired for the warp to travel from vat 6 overseaves 30 and 31 to vat 6 is sufficient for the dye in the warp tooxidize by exposure to the atmosphere; and each Warp 'eing supported onand traveling over sepa, rate sheaves prevents tanq'ling of the warp.due to breaking of a thread or threads in the warp as frequentlyoccursin the use of a continuoiis cylindrical roll.

The warpwinding machines being dupli cates, well known, and theirgeneral construction forming no part of my present in vention, a generaldescription thereof will Sui-iiCe- V 37 indicates the sides or frames ofthe machines, on which are vertical standards or supports 38,'whi ch areprovided with loosely mounted vertically movable =clamps 39-, having anextension 40 at one end which engages the axle of the beam and securesit ICO against lateral movement outward from the rate of speed as todraw the warp from the rolls 13' and maintain the tension of the warpfrom't-he time it leaves the beams 2 from which it unwound, until it isagain rewo'und on the beams 33 and 34. The effect of-this tensionon thewarp is to keep it free from kinks and tangles, in which condition ittravels through the vats and is readily and thoroughly impregnated withthe dye liquor, resulting in economy of dyeing material and time, andavoiding frequent repetitions of passing the warp through the liquor.

The practical operation of the invention has demonstrated a saving of atleast fifteen per cent. of dye material and fifty per cent. in labor,compared with the prevailing practice of dyeing warp, while the color ofthe dyed warp is absolutely uniform throughout the length of the warp,and consequently the fabric made from the warp is of uniform colorthroughout its length and width.

The Warp winding machines are each provided with a shaft 44 havingopposite spiral grooves 44, and are supported in bearings 45 on theframes 37 and are revolved by means.

()n the shaft 44 is also a traverse or carriage 48, see Figs. 4 and 5,having a vertical arm 49, on opposite sides of which are guide rolls 50,between which the warp travels, and a loop 51, prevents the warp jumpingofi the rolls. 52 are guide sheaves supported on arm 53, and arranged ata right angle to the rolls 50, and direct the warp to guide fingers Thecarrier-48 is connected to the spirally, grooved shaft 44, by a spanner55, provided with oppositely extending ends 56, which engage thegrooves, and the carrier is prevented turning on the shaft by an arm 57having a fork 58 engaging a transverse rod 59 between the frames 37.

Two strands of warp are wound or balled on the first winding machine 32,and the remaining two strands are conducted from the elevated sheaves 31to like sheaves 60 over which they pass to the second winding machine32, in which all the parts bear the same designating characters as inthe first machine.

The warp beams and their supporting frames are in alinement with the vat6 and the winding machines 32 and '32 are in alinement with the vat 6.

It is obvious that if a deeper shade of color is required than isproduced by exposure of the warp to the dye liquor in the two vats 6 6,the warp inav be conducted through other like vats until the desiredcolor is obtained.

The warp in traveling from one vat to the other and from the second vatto the winding machines, is exposed to the atmosphere, by which the dyeis oxidized or set in the warp after leaving each vat, thereby effectinggreat saving in the quantity of chemicals used in the dye li uor; and.by unwinding the warp from one eam orfrom beams, dyeing the warp intransit, and then winding the warp upon other beams, the cost ofhandling the warp. is also greatly reduced, and tangling, kinking andbreaking of the warp prevented.

The dyed warp is washed and is then removed to a suitable dryingapparatus where the warp is thoroughly dried.

It is my purpose to treat warp contin* uously, by first conducting itthrough vats and boiling the warp, then dyeing the warp, then washingthe warp, and then winding the warp on suitable beams. When it isdesired to bleach the warp, it is first conducted through-a boiling vat,then through a bleaching vat, then through a washing vat, successively.and continuously, and then winding the warp.

Having thus fully described my invention, what I claim is 1. Apparatusfor treating warp, comprising warp beams, and two vats side by sidecarrying drawing rolls whose ope'ratingshaft ,extends over both vats,separate sheaves mounted in series on shafts within the vats whereby thestrands of Warp move independently through the vats,both vats beingsimilar in construction and the entrance series of sheaves in one vatand the final series of the second vat so arranged that the warp travelscontinuously from its entrance into the first vat to its exit from thesecond vat.
